- 2 Claims. (Cl. 128-33) This invention relates to kinesitherapy appaconnecting the vibrator motor or driving means ratus and has as its principal object the proviwith a power circuit in the usual manner. sion of a device of this class including a vibrating The vibrator mechanism is constructed as a pedestal upon which the patron or patient stands, compact unit, and as shown in Fig. 4, lincludes 5 electrically driven means for vibrating the pedesthe base or pedestal portion l0 which is part of a 5 tal, coin-controlled mechanism forv actuating the base casting I5.

Thus, the housing and control mechanism may be said to constitute one unit, while the vibrating mechanism constitutes another unit readily detachable from the housing structure.

In' the operation of the device, the patron steps upon the treadle platform II and deposits a coin in the control device III, manipulating the latter in the usual manner to actuate suitable switch mechanism and start the motor 20. The eccen- Vtric rotation of the mass 23 about an axis approximately parallel with the plane of the platform results in the transmission of rapid and vigorous vibrations into the platform, which vibrations are communicated with maximum effectiveness into the body of the patron as a result of the particular mountingof the platform, particularly with respect to the resilient or spring termined lapse of time, the switch mechanism will shut off automatically and stop the motor.v

The various advantages and objects of the invention may be .accomplished by modifications of 'the particular embodiment specically described herein, and it is intended that the appended claims shall include all equivalent arrangements fairly coming within their call.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is: Y

1. In a` device of the class described comprising a base, a body supporting platform having an extended portion at one end thereof, a yieldable connection between the platform and the base at a point opposite the extended portion, a motor mounted on the extended portion on the top thereof remotely from the yieldable connection and including a shaft, resilient means providing a support between the extended portion and the base, an eccentric member on the shaft for transmitting vibratory action to the platform through the extended portion when said motor .is opera#- tive, and a vertically disposed housing enclosing said extension and said motor, that portion of the said platform on which a body is adapted to be supported being located between said housing and the point of said yieldable connection between the platform and the base.

2. A body vibrator comprising a vertically disposed housing, a base having a portion thereof confined in said housing; a platform exteriorv of the housing .and disposed over the exterior portion of said base and on which a person is adapted to stand and having an integral continuation extended into the housing providing an extended portion with the end of the extended portion substantially spaced from the adjacent end of the base, yieldable means providing a fulcrum between the exterior end portions of the platform and the base, spring means normally supporting the extended 'portion in Isaid spaced relation with respect to the interior portion of the base, a driven member mounted on the extended portion on the top thereof Within the holsing and including a shaft, and an eccentric member on the shaft for transmitting vibratory action to the platform through the extended portion when said ydriven member is operative, said eccentric including a screw member adjustable radially with respect to the shaft for varying the degree of v vibration transmitted to the said platform.
